Combine all ingredients in either a crockpot or an Instant Pot. If in the crockpot, fill to cover with water (can add more or less to accomplish this), turn to low and allow to cook for 12-24 hours. If in the Instant Pot, make sure you haven't filled past your max fill line (noted along the inside wall of the cooking vessel), set the pot to manual and allow to cook for 90-120 minutes.

Once done cooking, you can quick release (might spew some liquid along with the steam) or simply let the Instant Pot naturally release. 

Transfer to glass mason jars to store both in the fridge or freezer. You can also pour into ice cube trays and freeze, so you'll always have 1 ounce frozen cubes of the broth to quickly add and melt into any dish (my personal favorite!) 

Use in soups, braises and stews, or heat up and drink by the mugful with a pinch of sea salt.
